Objective:To observe the efficacy of cytokine-induced killer (CIK) cells on patients with advanced lung cancer. Methods:A total of 90 patients with advanced lung cancer were identified from January 2011 to December 2013. CIK therapy was given to 41 pa-tients in the observation group, whereas the other 49 patients in the control group received the best support treatments without che-motherapy or radiotherapy within one month of inclusion. Following up was conducted for the patients in the two groups, and KPS scores, median survival, and adverse reactions compared. Results:The KPS score in the observation group was higher than that of the control group after treatment (P=0.034). The median survival period of the observation group was eight months, which was one month longer than that of the control group (P=0.044). Major adverse reactions included fever, joint pain, and insomnia, which were recorded 51.22%, 36.58%, and 29.27%of occurrence, respectively. Conclusion:CIK cell therapy improved the quality of life and pro-longed the survival of advanced lung cancer patients with tolerable adverse reactions.

UNLABELLEDOBJECTIVE To observe the clinical efficacy by Qingying Huoxue Decoction (QHD) combined ursodeoxycholic acid (UDCA) in treating patients with early and mid-term primary biliary cirrhosis (PBC). METHODS Totally 78 patients were randomly assigned to the treatment group and the control group, 39 in each group. All patients received basic treatment and took UDCA (at the daily dose of 13-15 mg/kg). Patients in the treatment group took QHD, one dose per day. The treatment course for all was 6 weeks. Clinical efficacy, gamma-glutamyl transferase (γ-GGT), alkaline phospatase (ALP), TBIL, alanine aminotransferase (ALT), and aspartate transaminase (AST) were observed before and after treatment. RESULTS Totally 21 (53. 8%) patients obtained complete response in the treatment group, with statistical difference when compared with that of the control group (11 cases, 30. 8%). Levels of GGT, ALP, ALT, AST, and TBIL decreased in the two groups after treatment (P < 0.01). Levels of ALP, GGT, and TBIL were obviously lower in the treatment group than in the control group (P < 0.05).

CONCLUSIONSQHD combined UDCA in treating early and mid-term PBC patients was superior to the effect of using UDCA alone. It also could improve patients' liver function.

OBJECTIVETo evaluate the effects of sequential colon dialysis (SCD), hemodialysis (HD) and peritoneal dialysis (PD) on the serum level of uric acid (UA) in patients with hyperuricemia.

METHODSA total of 293 patients with mild, moderate and severe degree of hyperuricemia were randomly assigned to three groups according to digital randomized method, and treated with SCD, HD and PD respectively. The serum level of UA was determined with unicase-peroxidase conjugate method, the blood levels of K+, Na+, Cl-, Ca2+ were determined by automatic biochemical analysor, and changes of body weight were measured before and after dialysis.

RESULTSIn the 293 cases, the three modes of dialysis showed no difference in lowering uric acid in patients of mild degree (P > 0.05). But the HD did show a better efficacy than that of the other two in severe degree patients (P<0.01), while in patients of moderate degree, significant difference (P<0.01) showed between HD and SCD, PD and SCD, but not between HD and PD (P > 0.05). No obvious effect of the various modes of dialysis on the level of K+, Na+, Cl-, Ca2+, body weight.

CONCLUSIONSCD can decrease the serum level of UA effectively and reduce the incidence of complication of hyperuricemia to some extent, as hemodialysis and peritoneal dialysis can.

OBJECTIVE: To observe whether angiotensin II (AngII) influences expression of lectin-like oxidized low density lipoprotein receptor-1 (LOX-1) in cultured human umbilical vein endothlial cells(HUVECs). METHODS: Cultured HUVECs were incubated with 10(-5)mol/L approximate, equals 10(-10) mol/L AngII for 24 h or with 10(-6) mol/L AngII for various time up to 48 h. Then HUVECs LOX-1 protein expression was measured by endothlial cell enzyme linked immunosorbent assay, and mRNA level of LOX-1 was detected by quantitative competitive reverse transcription-polymerase chain reaction. RESULTS: Incubation of HUVECs with AngII for 24 h significantly increased LOX-1 protein expression (P<0.001). The increase was dependent on AngII concentration (10(-5)mol/L approximate, equals 10(-9)mol/L). LOX-1mRNA expression was also induced by AngII, and after 24 h incubation of AngII(10(-5)mol/L approximate, equals 10(-8)mol/L), LOX-1mRNA expression increased 4.43, 4.25, 2.71, 1.84 times, respectively. After treatment with 10(-6) mol/L AngII for 3 h, LOX-1 expression (protein and mRNA) was elevated (P<0.001) in HUVECs, reaching its maxium at 24 approximate, equals 36 h. CONCLUSION: AngII upregulates LOX-1 expression concentration-dependently and time-dependently in HUVECs.

Objective To construct erythromycin-overproducing mutants by tandemly expressing S-adenosylmethionine synthetase gene metK, Vitreoscilla hemoglobin gene vhbS and pleiotropic regulatory gene adpA in Saccharopolyspora eryth-raea.Methods Through PEG-mediated protoplast transformation , the integrative plasmid carrying metK, vhbS and adpA was respectively introduced into erythromycin-producing wild-type strain S.erythraea A226 and industrial strain WB .The engineered strains were generated by apramycin resistance screening and PCR identification .The erythromycin production was compared in original strains and their mutants by the inhibition test of Bacillus subtilis and HPLC analysis .Results and Conclusion Four A226-derived mutants A226-P1-P4 and three WB-derived mutants WB-P1-P3 were independently obtained.Compared with wild-type strain A226, the relative erythromycin titer of the four engineered strains A 226-P1-P4 was increased from 8%to 25%by scoring the growth-inhibition zones .Further HPLC analysis showed that the four mutants had increased erythromycin A yield by 64%-94%.Likewise, the relative erythromycin titer and erythromycin A yield of the three engineered strains WB-P1-P3 were enhanced by 6%-10%and 31%-62%, respectively, in comparison with the original strain WB.The results show the universality of enhancing erythromycin productionvia tandem expression of metK, vhbS and adpA in S.erythraea.

Objectives To reveal etiologies of persistent isolated hematuria (PIH) through ultrastructural pathological examination, to disclose clinicopathological correlation in cases with PIH, and to summarize appropriate management of patients with PIH.
Methods we retrospectively studied 155 PIH patients receiving renal biopsy between January, 2003 and December, 2008 in Peking Union Medical College Hospital. All the clinical data and follow-up result were analyzed.
Results All subjects included 38 children and 117 adults, with mean age of 11.38±3.25 years for children and 35.17±8.44 years for adults. Thin basement membrane nephropathy (TBMN) was the most common pathology (55.3% of children and 49.6% of adults), followed by IgA nephropathy (18.4% of children and 32.5% of adults, mainly grade 2-3) and mesangial proliferative glomerulonephritis (MsPGN) without IgA deposition (13.2%of children and 12.8%of adults). Besides, Alport syndrome (2.6%of children) and membrane nephropathy (2.6%of children and 0.9%of adults) were demonstrated as other causes of PIH. Elevated mean arteral pressure or protein excretion rate, as well as episodic macrohematuria, indicated higher risk for MsPGN rather than TBMN. On the other hand, severity of microhematuria was irrelevant to pathological types of PIH. Totally, 86 patients were followed up and 37 cases therein stayed on track for long term (mean duration 41.11±28.92 months, range 8-113 months). Most cases had benign clinical course except 3 cases with TBMN, 5 cases with IgA nephropathy, 1 case with MsPGN (without IgA deposition), and 1 case with Alport syndrome, who developed hypertension or proteinuria. All of them were administered timely intervention.
Conclusions Close follow-up should be required as the primary management for PIH. Equally important is careful monitoring for early identification of undesirable predictors;while renal biopsy and other timely intervention are warranted if there is hypertension, significant proteinuria or renal impairment.

Objective To observe apelin and its receptor (APJ) expressions in human osteoblasts and evaluate the effect of apelin on osteoblasts.Methods The expressions of apelin and APJ in human osteoblasts were tested by RT-PCR and Western blot.After human osteoblasts were treated with apelin,cell proliferation was measured by [~3H] thymidine incorporation and cell counting.Cell function was measured by alkaline phosphatase (ALP) activity,the secreted osteocalcin level and typeⅠcollagen production .The activation of signaling cascades was tested by Western blot.Small-interfering RNA (siRNA) to blockade APJ was applied to observe effects of apelin on cell proliferation and the activation of signaling cascades.Results Both apelin and APJ were expressed in human osteoblasts.Apelin increased the proliferation and did not show the influences on ALP activity, osteocalcin secretion and type I collagen production in human osteoblasts.Apelin induced activation of phosphatidylinositol-3 kinase (PI3K) downstream effector (Akt),but not mitogen-activated protein kinase (MAPK) such as c-jun N-terminal kinase (JNK),p38 and ERK1/2 in human osteoblasts.Suppression of APJ with siRNA or LY294002 (PI3K inhibitor) abolished the apelin-induced cell proliferation and the activation of Akt.Conclusion Human osteoblasts express apelin and APJ.Apelin stimulates the proliferation of human osteoblast via APJ/PI3K/Akt pathway,but has no effect on osteoblast differentiation.
